Using the R2RML method of generating semantic RDF triples in Oracle 12c

One model successfully created without any problems but then moved to a bigger one and were able to generate around 3,500 of the mapped triples into the staging table before it runs into an error when we call sem_apis.export_rdfview_model:

the URL instead.
